Sgs 07369 Circuit Board Drill Bit Size 42 Solid Carbide

Product Description

The SGS 07369 is a solid carbide circuit board drill bit engineered for precision drilling in printed circuit boards and other thin, demanding materials. It runs a wire size 42 diameter of 0.0935 inches with a 1/8-inch shank diameter and an overall length of 1.5 inches. The 130-degree four-facet point geometry reduces thrust and promotes accurate entry without walking. The uncoated solid carbide construction provides the rigidity and heat resistance required when drilling hard, abrasive, or layered substrates. This bit is suited for electronics manufacturing, precision machining shops, and fabrication environments where tight tolerances are non-negotiable.

The SGS 07369 is designed for use in CNC drilling machines and precision drill presses where circuit board and small-diameter hole work is common. Its regular spiral with a 30-degree helix angle and tapered web configuration supports effective chip evacuation in shallow, high-speed drilling passes. The material application range covers aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium, making it a versatile option across electronics and light machining applications.

Key Features

• Wire size 42 diameter (0.0935 inches) for precision small-hole drilling
• 130-degree four-facet point for reduced thrust and accurate entry
• Solid carbide construction for rigidity and wear resistance in hard materials
• 1/8-inch shank diameter compatible with standard drill chucks and collets
• Right-hand cut with regular spiral and 30-degree helix for clean chip evacuation
• Uncoated finish suitable for a wide range of workpiece materials

Compatibility

Designed as a direct-fit replacement or new-install option for CNC circuit board drilling operations requiring a wire size 42 solid carbide bit with a 1/8-inch shank; compatible with workpiece materials including aluminum, cast iron, cobalt alloy, copper alloy, fiber-reinforced polymers, nickel, plastics, stainless steel, and titanium.

Installation Notes

This bit should be installed by a qualified machinist or CNC operator in a machine spindle or drill chuck rated for small-diameter carbide tooling. Ensure the machine is fully powered down and spindle is locked before changing tooling. Solid carbide bits are brittle - avoid side loading, excessive feed rates, or interrupted cuts that can cause chipping or breakage. Confirm runout and chuck concentricity before drilling to maintain the tight diameter tolerance of -0.0003 to +0.0000 inches.
